From the foregoing description it will be seen that the ventilator is inthe nature of an open work post adapted to be centrally i located in thehaystack as shown in Figure r and clogging it.

When using two or more sections as seen in the drawings it may be wellto provide supplemental means for fastening the sections together andthis means may be in the nature of a simple duplex fastener of the typeillustrated in Figure 7. This comprises a pair of duplicate bendablemetal bars 28 fastened together by a tie cord or wire 29 to facilitatemaintenance and guard against accidental loss. rlhese straps are formedof bendable metal so that they may be placed around the rings 10 and 18as shown in Figure 4. The opposite ends are bent into the form of hooks30 and 31 thereby facilitating application and removal and insuring agreater rigidity to guard against displacement of the sections of thedevice after it is assembled in a hay stack.

It is manifest that a device constructed in accordance with theprinciples of this in- .vention is simple, effective, capable ofexpeditious installation and handling either during the time oftransportation or erection.

It is understood that the invention serves not only as a convenientmeans in the field for stacking hay but is also advantageous for usewithin barns and similar buildings. In fact, several of these devicesmay be installed lin a barn with reasonable assurance against firehazards.

It is'thought that the description taken in 'connection with thedrawings will enable a clear understanding of the invention to be had.Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown anddescribed, it is to be understood that minor changes coming within thefield of invention claimed may be resorted to if desired.

Having thus described my invention, what l claim as new Iis:

1. A hay stack ventilator and erecting deviceI of the class describedcomprising a lower section including upper and lower rings ofcorresponding diameter, a plurality of vertical metal straps attached tothe exterior faces of said ring, the upper ends of the straps beingiiush with the upper edge of the uppermost ring, the lower ends thereofextending below the lowermost ring and directed laterally outward andapertured for anchoring purposes; and an upper companion sectionincluding upper and lower rings together with a plurality ofcircumferentially spaced vertically extending straps attached to saidring, the rings of said upper section corresponding yin diameter tothose of the lower section, and the lower ends of the strap niembersthereof extending below the lowermost ring and fitting down over theupper ring of the lower section and the adjacent rings of said sectionsbeing in abutting relationship.

2. A hay stack ventilator and erecting device of the class describedcomprising a lower section including upper yand lower rings ofcorresponding diameter, aV plurality of vertical metal straps atached tothe 'exterior faces ofsaid ring, the upper ends of the straps being iushwith the upper edge of the uppermost ring, the lower ends thereofextending below the lowermost ring and directed laterally outward andapertured for anchoring purposes; and an upper companion sectionincluding upper and lower rings together with a plurality ofcircumferentially spaced vertically extending straps attached to saidring, the rings of said upper section correspending in diameter to thoseof the lower section, and the lower ends of the strap members thereofextending below the lowermost ring and fitting down over thev upper ringof the lower section and the adjacent rings of said sections being inabutting relationship, and a removable closure comprising a ring adaptedto seat on the uppermost ring of the upper section and includingdepending retaining elements to removably retain the cap in place.

In testimony whereof I aiiix my signature.

WALTER TISHAUSER.
